Design and optimization of energy-efficient multicomponent distillation configurations

Process modelling, simulation and optimization are very efficient methods and tools to design and optimize industrial distillation plants in both new processes and process retrofits. Combined with distillation synthesis and intensification, we can design and optimize distillation plants for energy savings, for capital reductions, for debottlenecking and increasing production capacity, as well as optimal operations. The distillation processes cover ordinary distillation, azeotropic distillation, extractive distillation and distillation hybrid with other separation techniques. 

At the SDU-ChE section, important milestones have been achieved in different topics related to separations by distillation:

  1. Developing of design and optimization methods able to take advantages from the synthesis procedure, resulting in reliable and fast methodology.
  2. Application of the design and optimization methods to specific cases of industrial separation problems.
